# --description--

Two or more strings can be concatenated by using the `+` operator. For example: `'Hello' + ' there!'` results in `'Hello there!`.

Call the `print()` function and use the `+` operator to concatenate the `text` variable to the string `'Encrypted text: '`. Pay attention to the spacing.

# --hints--

You should call `print()` and pass `'Encrypted text: ' + text` as the arguments.

```js
const commentless_code = __helpers.python.removeComments(code);
assert.match(commentless_code, /^print\s*\(\s*("|')Encrypted\stext:\s\1\s*\+\s*text\s*\)/m)
```

Your code contains invalid syntax and/or invalid indentation.

```js
({test: () => assert(true) })
```

    for char in message.lower():

        # Append any non-letter character to the message
        if not char.isalpha():
            final_message += char
        else:        
            # Find the right key character to encode/decode
            key_char = key[key_index % len(key)]
            key_index += 1

            # Define the offset and the encrypted/decrypted letter
            offset = alphabet.index(key_char)
            index = alphabet.find(char)
            new_index = (index + offset*direction) % len(alphabet)
